The overlapping photos of site 4 from 2002. The erosion rate iscalculated for the rock wall of this site.

Conclusions and future work

The method of close up digital terrestrial photogrammetry seems suitablefor creating accurate digital terrain models of coastal cliffs and hencepromising for detecting changes in the order of mm to cm/year. André(1997) reports of Holocene rock wall retreat in the range 0 to 1.58 mm/yin the same area.

The fieldwork was financially supported by the INTAS-project“Arctic coasts of Eurasia: dynamics, sediment budget and carbon flux in connectionwith permafrost degradation” (INTAS-2001-2329) and by two scholarships from theNorwegian Research Council on behalf of the Norwegian Polar Committee .
